Appearing in the Senate for a photo session in 2004, then-Vice President Dick Cheney told Democratic Vermont Sen. Patrick Leahy to “fuck yourself.”

Cheney, who was reportedly upset by Leahy’s criticism of Halliburton’s role in rebuilding Iraq, stood by his remarks to Leahy years later on Fox News Sunday.

“I thought he merited it at the time and we’ve since patched over that wound,” he told host Chris Wallace in 2008.

Watch:

Arizona Sen. John McCain, always rumored to have a healthy temper, reportedly exploded at Texas Republican Sen. John Cornyn in 2007 during negotiations over comprehensive immigration reform because he felt that McCain was “parachut[ing]” into the negotiations from the presidential campaign trail.

“Fuck you!” McCain reportedly remarked in tone above a normal talking voice. “I know more about this than anyone else in the room.”
